具有良好的水分散性和稳定性的具有负载的过渡金属颗粒的聚合物胶囊及其制备方法

POLYMER CAPSULE HAVING LOADED THEREON TRANSITION METAL PARTICLES HAVING EXCELLENT WATER DISPERSIBILITY AND STABILITY, AND METHOD FOR PREPARING SAME
Abstract:
Provided are a polymer capsule loaded with transition metal particles having excellent water dispersibility and stability, and a method for preparing the same. Specifically, the polymer capsule loaded with transition metal particles according to the present invention includes a surface-modified polymer capsule surface-modified to thereby have a positive zeta potential in a dispersed state in water; and transition metal particles loaded on a surface of the surface-modified polymer capsule. In addition, a method for preparing a polymer capsule loaded with transition metal particles according to the present invention includes a) preparing a polymer capsule; b) surface-modifying the polymer capsule to prepare a polymer capsule having a positive zeta potential in a dispersed state in water; and c) sequentially adding a water-soluble transition metal precursor and a reducing agent to a water dispersion of the surface-modified polymer capsule obtained in step b).
Abstract(Chinese):

提供一种装载有具有优异的水分散性和稳定性的过渡金属颗粒的聚合物胶囊及其制备方法。 具体地说，根据本发明的装有过渡金属颗粒的聚合物胶囊包括表面改性的表面改性聚合物胶囊，从而在水中分散状态具有正的ζ电位; 以及负载在表面改性聚合物胶囊的表面上的过渡金属颗粒。 另外，本发明的负载有过渡金属粒子的聚合物胶囊的制备方法包括：a）制备聚合物胶囊; b）对聚合物胶囊进行表面改性以制备在水中具有分散状态的正ζ电位的聚合物胶囊; 和c）依次向步骤b）中获得的表面改性聚合物胶囊的水分散体中加入水溶性过渡金属前体和还原剂。
